The default is 1 The preconditioner is ALWAYS built in the first iteration
of a nonlinear solve unless lag is *-1* or SNESSetLagPreconditionerPersists
<https://www.mcs.anl.gov/petsc/petsc-current/docs/manualpages/SNES/SNESSetLagPreconditionerPersists.html#SNESSetLagPreconditionerPersists>()
was called

Should it be -2 :
